ROH Sec. 21-4.60 sets the maximum structure heights for Kapolei, pairing absolute caps with sloped building envelope planes so tall second stories stay away from property lines.
Height limits in Kapolei vary significantly by district. Most single-family neighborhoods apply a 25 to 30 foot cap with envelope planes from each side yard, while mixed-use and apartment districts around the Kapolei town center allow more substantial heights. ROH 21-4.60 governs how heights are measured, and 21-3.70-1 cross-references residential-specific caps. Rooftop equipment, chimneys, and solar arrays often qualify for limited exceptions. Commercial and industrial lots follow district-specific rules. Understanding both the absolute limit and the envelope plane is key to successful Kapolei additions and new builds.
Plan check rejections, redesign costs, and fines where built work exceeds the allowed height or envelope plane.
